Description

Method and apparatus for triggering aperiodic feedback in coordinated multiple points transmission

The triggering method and engineering device technique field of non-periodic feedback in coordinated multipoint transmission

The present invention relates to the transmission technology in communication system, more specifically to the triggering method and device of the non-periodic feedback that coordinated multipoint transmission is supported in a kind of lte-a system.Background technology

LTE-A (Long Term Evolution- Advanced, enhanced Long Term Evolution）In system, multipoint cooperative (CoMP, Coordinated Multiple Points) transmission technology is introduced for strengthening the performance of Cell Edge User, while improving the average throughput of cell.Descending CoMP technologies are standardized work for following three kinds of schemes in LTE-A 11：Joint transmission（Joint Transmission, JT), dynamic transmission point selection（Dynamic Point Selection), cooperation scheduling/wave beam forming（Coordinated Scheduling/Beamforming).Link circuit self-adapting transmission is carried out in order to accurate, the gain of CoMP transmission, user terminal is effectively obtained（UE, User Equipment) need to assume feedback accurate PMI (Preceding Matrix Indicator, pre-coding matrix instruction for different transmission）(Channel Quality Indication, channel quality is indicated/CQI）/ RI (Rank Indication, order instruction）Information.Determine at least to support that (Channel State Indication- S, channel status indicates reference signal to each CSI-RS in the meetings of 3GPP RAN1 67）The feedback scheme of resource.Determine that CoMP measurement collection could support up three CSI-RSs in the meetings of 3GPP RAN1 68.Because mobile station is limited by actual treatment ability, specific CSI reports quantity further to limit.In fact, in the presence of the compromise of a feedback overhead and system performance gain.More feedback information advantages systems obtain the gain of CoMP transmission.On the other hand, it also increases the expense of uplink feedback.

In LTE Rel.10 systems, cycle and aperiodic feedback system are utilized for base station and provide varigrained feedback information, improve the performance of system.Non-periodic feedback has feedback capacity big, the small advantage of time delay, is adapted to CoMP feedback needs.Therefore need to design effective trigger mechanism to support non-periodic feedback in CoMP transmission.

At present, non-periodic feedback passes through DCI (Dynamic Control Information, Dynamic control information）To trigger.When user is configured without multi-carrier transmission, reported using 1 bit CSI request domain in DCI format 0 or DCI format 4 to trigger the aperiodic of associative mode；When user configuring multi-carrier transmission, reported using 2 bit CSI request domains in DCI format 0 or DCI format 4 to trigger the aperiodic of associative mode.As shown in table 1, wherein 00 representative is not triggered and reported；01, which represents triggering, reports the aperiodic of main carrier；10 and 11 represent triggering high level The set 1 of configuration and reporting for set 2.Wherein set 1 and 2 is configured by high-level signaling, and the high-level signaling indicates which of 8 subcarriers need to report by the message bit pattern of 8 bits.At present, lte-a system maximum supports 5 subcarriers, thus it is actual be up to 5 bits and be set to 1, namely be set to the 1 corresponding subcarrier of bit and need to report.It is triggered in addition, aperiodic ought report in public search space, in order to meet the length requirement of DCI information, only supports the signaling of 1 bit to trigger.When user is configured as multi-carrier transmission, it is contemplated that carrier wave is again with being a kind of scene of important use public search space transmission DCI information, when 1 bit triggering signaling puts 1, the corresponding descending carrier only with triggering up non-periodic feedback carrier wave（Defined in system information block 2）CSI information fed back.

The implication in the CSI domains of table 1 is explained

Inventor has found that the CSI information of user feedback includes Rank Indication (I, order instruction during the present invention is realized）, Precoding Matrix Indication (PMI, pre-coding matrix instruction）, Channel Quality Indication (CQI, channel quality is indicated) information.Base station is the CSI-RS resources and interference sections measurement resource for the non-zero power that each CSI is configured, and user is using these resource measurements CSI and reports.In CoMP transmission, due to multiple CSI information（Correspondence different transfer point and interference hypothesis）Need to report, feedback overhead is very big.

Referring to the drawings, by following specification, the foregoing and further feature of the embodiment of the present invention will be apparent.These embodiments are exemplary, are not limitations of the present invention.In order that those skilled in the art can easily understand that the principle and embodiment of the present invention, embodiments of the present invention are illustrated by taking the triggering method of the non-periodic feedback in CoMP transmission in lte-a system as an example, it is to be understood that, the embodiment of the present invention is not limited to said system, is applicable for being related to the other systems of triggering of non-periodic feedback.

Below in an example, the method that DCI and high-level signaling are combined has been continued to use, with the flexibility and the preferable compromise of signalling loads size of the triggering for obtaining non-periodic feedback.In order that the method for the embodiment of the present invention understand it is understandable, below by way of different application scenarios, such as scene of user search space triggering（The scene that CoMP transmission scene, CoMP and CA are combined）And the scene of public search space triggering（CoMP transmission scene, the scene that CoMP standing grain B CA are combined）, the triggering method to the non-periodic feedback of each of the invention embodiment illustrates.But, the triggering method of non-periodic feedback under each scene is not independent, the scene that such as CoMP and CA is combined can also use the triggering method in CoMP transmission scene, public search space triggering method can also use the triggering method of user search space in CoMP transmission scene, will be illustrated respectively below.

The CoMP transmission scene of non-periodic feedback is triggered in user search space

In lte-a system, in order to support the CSI information under CoMP transmission, different transfer points and interference hypothesis to need feedback.In order to obtain feedback flexibility and the compromise of signaling consumption, the method that the embodiment of the present invention is combined using dynamic DCI and high-rise RRC signaling.

Embodiment 1

The embodiments of the invention provide a kind of triggering method of the non-periodic feedback in coordinated multipoint transmission.Fig. 1 is the flow chart of this method, refer to Fig. 1, and this method includes： Step 101:Base station sends Dynamic control information to UE（DCI) and the correspondence DCI feedback set that is pre-configured with, to trigger the non-periodic feedback that UE carries out corresponding channel condition information according to the DCI and the correspondence DCI feedback set.

In the present embodiment, the non-periodic feedback is triggered in user search space, therefore, and the DCI signalings can reuse 2 bit informations in DCI formatO or DCI format4 CSI request domain.That is, when aperiodicity feedback（Report）When being triggered in user search space, base station passes through the CSI request signaling to UE 2 bits of transmission（DCI) come trigger UE carry out CSI information non-periodic feedback.In one embodiment, indicate not triggering aperiodic report for the DCI of 2 bit, 00；01,10,11 indicates respectively the feedback set 1 of the high-rise configuration of triggering, reports feedback set 2, the aperiodic of feedback set 3.In another embodiment, indicate not triggering aperiodic report for the DCI of 2 bit, 00；01 indicates triggering anchor cell（Main plot or some specific single cell）CSI is reported；10,11 indicate respectively the feedback set 1 of the high-rise configuration of triggering, report the aperiodic of feedback set 2.

In the present embodiment, correspondence DCI each non-full zero bit, for example, 01,10,11, base station has been pre-configured with corresponding feedback set, namely above-mentioned feedback set 1 or feedback set 2 or feedback set 3, so as to contents of the UE according to indicated by the DCI received bit and corresponding feedback set, carry out corresponding CSI non-periodic feedback.

In the present embodiment, if the CSI set of periodic feedback is the subset of the CSI set of non-periodic feedback, base station directly passes through high-level signaling（RRC signaling）The instruction that one CSI set of configuration can just be fed back with performance period and aperiodic CSI, wherein, aperiodic CSI feedback is directly gathered using this.If the CSI set of non-periodic feedback can not include periodic feedback CSI set, the CSI needed for base station will not only configure a joint feedback by high-level signaling gathers, and to be also that non-periodic feedback configures CSI set by high-level signaling.Now, the above-mentioned correspondence being pre-configured with DCI feedback set is selected from the high-rise CSI set configured for non-periodic feedback.

Wherein, the feedback set for the correspondence DCI being pre-configured with can be classified according to the transmission point of triggering or the CSI-RS of non-zero power, can also be classified according to the CSI of configuration, can also be classified according to interference type.

In one embodiment, feedback set is according to the transmission point of triggering（) or the CSI-RS of non-zero power is classified TP.Then in the present embodiment, each feedback set is used for the corresponding CSI set of the CSI-RS of transmission point or non-zero power for indicating to need to trigger, for example, feedback set 1,2,3 represent the corresponding CSI set of transmission point or non-zero power CSI-RS of triggering respectively.In this example, it is assumed that the size that CoMP measurements integrate is N, then the feedback set can pass through wireless heterogeneous networks（RRC) bitmaps of the N bits of signaling is indicated, wherein, the transmission point being triggered is set to 1 in the bitmap of the N-bit.By taking N=3 as an example, namely the size of CoMP measurement collection is 3, There can be 3 transmission points to carry out CoMP transmission, it is assumed that there are two transmission points to be triggered in feedback set 1, then should

In the bitmap of 3 bits of RRC signaling, the bit for corresponding to the two transmission points is set to 1, as shown in Figure 2 a.

In the present embodiment, because each non-zero power CSI-RS may correspond to different interference hypothesis, it can include multiple CSI information.Therefore, the present embodiment can also classify according to non-zero power CSI-RS to feedback set, that is, the feedback set, which is indicated, reports all CSI information for including non-zero power CSI-RS in possible non-periodic feedback CSI set.

In the present embodiment, in order to increase flexibility, base station can also be pre-configured with for each non-zero power

CSI-RS needs the interference hypothesis fed back, so that UE carries out the non-periodic feedback of corresponding channel condition information according to the interference hypothesis.The interference hypothesis can also be configured by RRC signaling, still measure the size that integrates exemplified by N by CoMP, in the present embodiment, can by 2 (^Ν_^υThe RRC signaling of individual bit configures the interference hypothesis, wherein the CSI information put per bit under the corresponding interference hypothesis of 1 explanation needs feedback.

In another embodiment, feedback set is classified according to the CSI of configuration.Then in the present embodiment, each feedback set is used for the CSI set for indicating to need to trigger.For example, feedback set 1,2,3 represents the CSI set for needing to trigger respectively.

In the present embodiment, the feedback set can be indicated by the bitmap of the Μ bits of RRC signaling, wherein,

Μ is the size for the CSI set that base station is non-periodic feedback configuration or the size of the maximum aperiodic CSI set reported that can be supported of user.Such as Μ=5 or 6.Wherein, the bit for putting 1 represents to need to feed back corresponding CSI information, and by taking Μ=5 as an example, the indicating mode of the feedback set is as shown in Figure 2 b.By this sorting technique, indicate that the granularity of non-periodic feedback is finer.

In another embodiment, feedback set is classified according to interference type.Then in the present embodiment, each feedback set is used to indicate the corresponding CSI set of possible interference type.For example, feedback set 1,2,3 represents reporting for possible interference type respectively.

In the present embodiment, the size integrated is still measured exemplified by N by CoMP, due to having 2^(N— ¹The possible interference type of ＞ kinds, therefore the feedback set can pass through 2^(N— ¹The RRC signaling of ＞ bitmap bit indicates that it represents the interference type for needing to report.That is, in the CSI set of non-periodic feedback, the CSI (CSI assumed comprising multiple non-zero power CSI-RS) of all interference types comprising indicated by the feedback set needs to report.For example, indicating to gather the CSI information reported in 1,2,3, it is necessary to which 4 bits are respectively adopted for 3 CoMP set for measurement collection size.

In each embodiment more than, the non-periodic feedback of Dynamic trigger can be indicated using new RRC signaling Feedback set.RRC signaling as shown in Figure 2 a and 2 b；Carrier aggregation system can also be reused（CA 8 bit RRC indication signalings in) indicate the CSI feedback set of the non-periodic feedback of Dynamic trigger, and the present embodiment is not in this, as limitation.As long as feedback set is classified according to aforesaid class method, and to should sorting technique, configuration corresponding bits number RRC signaling the feedback set is indicated, be all contained in protection scope of the present invention.

UE is triggered by the method for the present embodiment and carries out non-periodic feedback, UE is no longer by all CSI information（Multiple CSI information under the conditions of the different transfer point of correspondence and interference hypothesis）Report, but the condition selectively limited according to feedback set is reported, or only report the corresponding CSI set of transmission point of triggering, or only report the corresponding CSI set of CSI-RS of non-zero power, or only report the CSI of triggering to gather, or only report the corresponding CSI set of some interference types, thus solve in CoMP transmission, because multiple CSI information of the different transfer point of correspondence and interference hypothesis need the problem of feedback overhead is big caused by reporting, feedback flexibility and the preferable compromise of system signaling expense are realized.

In the present embodiment, assuming that DCI 2 bit informations 01,10,11 represent the feedback set 1,2,3 of the high-rise configuration of triggering respectively, if the DCI that then UE is received is 10, feedback set 2 is then triggered, contents of the UE according to indicated by the feedback set 2 of high level configuration carries out the non-periodic feedback of corresponding CSI information.If for example, the bitmap for the N-bit that the feedback set 2 of high-rise configuration passes through RRC signaling（N is the size that CoMP measures collection）Indicate The transmission point of triggering, then UE only report the transmission point of triggering corresponding CSI set；If the bitmap for the N-bit that the feedback set 2 of high level configuration passes through RRC signaling indicates the CSI-RS of non-zero power, UE only reports the corresponding CSI set of the CSI-RS of non-zero power；If the bitmap for the M-bit that the feedback set 2 of high level configuration passes through RRC signaling（M is the CSI set that high level is non-periodic feedback configuration）The CSI set of triggering is indicated, then UE only reports the CSI of triggering to gather；If high level configuration feedback set 2 pass through RRC signaling 2^(Ν"^υIndividual bit indicates the interference type for needing to report, then UE only reports the corresponding CSI set of these interference types.

By the method for the present embodiment, UE is no longer by all CSI information（Multiple CSI information under the conditions of the different transfer point of correspondence and interference hypothesis）Report, but the condition selectively limited according to feedback set is reported, thus solve in CoMP transmission, because multiple CSI information of the different transfer point of correspondence and interference hypothesis need the problem of feedback overhead is big caused by reporting, feedback flexibility and the preferable compromise of system signaling expense are realized.
